Built in Maine. 

Trusted Since 1979.

Our story began in the 1970s when structural designer, Fremont Merriam needed a dock for his lake house in Maine. Unable to find a suitable solution in his community, he embarked on an adventure to design and build his own. The dock had to be strong enough to withstand the harsh conditions of a large lake, yet lightweight enough for annual removal and reinstallation to avoid winter ice damage.

Once the dock was complete, Fremont realized it wasn’t just a great solution for his own needs—it could also help countless others seeking reliable access to their waterfront. Inspired to fill this gap, he decided to turn his passion into a business dedicated to creating great waterfront solutions. With a vision for both quality and service, Fremont, alongside his sons, set out to design and produce the most dependable docks and dock hardware on the market.

Guided by a commitment to excellence, Fremont emphasized not only product durability but also an exceptional customer experience. Under his leadership, Great Northern Docks was founded on a solid foundation of integrity—a legacy that has remained strong for over 45 years.

At Great Northern Docks, craftsmanship runs deep. Now in our third generation of family ownership, we continue to handcraft what many consider the highest-quality aluminum docks and stairs available today.
